Cooling polishing improvement process for fine processing of rice

Abstract

The invention discloses a cooling polishing improvement process for fine processing of rice. The cooling polishing improvement process comprises the steps that unhusked rice enters a grain vertical silo, a precleaner, a permanent magnet cylinder, a vibrating cleaner, a stoning machine, a main rice husker, an auxiliary rice husker, a first rice mill, a second rice mill, a third rice mill, a polisher, a color sorter, a white rice grader, a length grader, a finished product vertical silo, an electronic flow balance and packages in sequence. A primary cooling silo integrating the functions of selection, husked rice separation and rice temperature reduction is arranged between the first rice mill and the auxiliary rice husker. A secondary cooling silo integrating the functions of screening and rice temperature reduction is arranged between the polisher and the third rice mill. The cooling polishing improvement process for fine processing of rice aims at solving the problems that through an existing cooling polishing process for fine processing of rice, the processing procedure chain is long, efficiency is low, and the temperature reduction effect is not obvious.

Description

technical field [0001] The invention relates to the technical field of food finishing, in particular to an improved cold polishing process for rice finishing. Background technique [0002] At present, during the finishing process of rice, the temperature of the rice is getting higher and higher due to the friction between the processing machinery (especially the emery roller rice mill, etc.) and the rice, and the excessive temperature of the rice during the processing will damage the rice grains The internal physical properties of the rice grains make the rice grains soft and brittle. Therefore, in the existing processing process, there is a cooling process in the polishing machine through mechanical air blowing or adding a conveyor belt in front of the polishing machine. However, these mechanical cooling methods The results are not ideal. When the rice comes out of the rice mill, the rice temperature is generally around 45°C. The polishing process in this form is called the...
